George and Harold are planning a toilet paper ( TP for short ) prank on the whole school by covering the whole school with toilet paper and claiming they will be legends. Meanwhile, so many TP had come to the school for Mr. Krupp to impress a new boring French teacher named Ms. Yewh comes to the school for French Week. George and Harold steal the TP for their prank, but it backfires and they have to clean up the whole school. They are finished and they sell a new comic about Ms. Yewh, but Mr. Krupp confiscates all the comics to impress Ms. Yewh and throws them in the toilet. George and Harold notice it's flooding, so they put a whole jug of unclogging liquid, even though it gave a warning not to put too much. Meanwhile, Ms. Yewh finds a comic and reads it. It is completely rude to her, so she flushes the comic down the toilet. But a combination of too many comics and a full jar of unclogging liquid in the toilet turns her into the TP Mummy.
